1N6627/TR

Overview

The Microchip Technology 1N6627/TR is a single fast recovery rectifier designed for high-speed switching applications. It features a maximum repetitive reverse voltage of 400 V and an average forward current rating of 4 A. The device exhibits a typical forward voltage drop of 1.5 V at rated current and a low reverse leakage current of 2 uA. Key performance metrics include a maximum surge current capability of 75 A and a rapid reverse recovery time of 45 ns. It operates within a junction temperature range of -65°C to +150°C and utilizes the E-Package-2 through-hole configuration.

Feature Summary

• Fast recovery characteristics with a 45 ns reverse recovery time for efficient high-frequency operation
• Robust thermal management supporting a maximum junction temperature of +150°C
• High surge current handling capability up to 75 A for transient protection
• Low reverse leakage current of 2 uA to minimize power loss in blocking state

Applications

• High-frequency DC-DC converter circuits
• Free-wheeling diodes in motor drive systems
• Snubber circuits in power supplies
• General-purpose fast switching rectification

Procurement Notes

Verify the specific ordering suffix against official Microchip documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with RoHS exemptions if required by the end application. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before procurement.

Selection Notes

Select this component when a 400 V reverse voltage rating and 4 A continuous current are required in a through-hole format. The 45 ns recovery time makes it suitable for frequencies exceeding standard rectifier capabilities. Compare against similar series parts like the 1N6628 or 1N6630 if higher voltage ratings are needed while maintaining comparable current handling.

Part Context

This component belongs to the 1N66xx series of fast recovery rectifiers manufactured by Microchip Technology. The series offers various voltage ratings from 200 V to 990 V, all sharing similar fast recovery characteristics and robust construction. The 1N6627 variant specifically targets applications requiring a balance between 400 V blocking capability and 4 A current capacity.
